General Description
The MAX1449 +3.3V, 10-bit analog-to-digital converter (ADC) features a fully differential input, a pipelined 10-stage ADC architecture with wideband track-and-hold (T/H), and digital error correction incorporating a fully differential signal path. The ADC is optimized for low power, high-dynamic performance in imaging and digital communications applications. The converter operates from a single +2.7V to +3.6V supply, consuming only 186mW while delivering a 58.5dB (typ) signal to-noise ratio (SNR) at a 20MHz input frequency. The fully differential input stage has a -3dB 400MHz band width and may be operated with single-ended inputs. In addition to low operating power, the MAX1449 features a 5µA power-down mode for idle periods.
